OF MANNING, IOWA.

ADJUSTABLE SEATELI FT CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 297,933, dated April29, 1884.

Application filed December 3], 1883. (No model.)

To all whom, it may concern.- Be it known that we, CHARLES H. HILL andJAMES T. BYAN, of Lombardville and Manning, in the counties of Stark andCarroll, in the States of Illinois and Iowa, respectively, have inventedan Improved Cultivator; and we do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theannexed drawing, making a part of this specification, in which likeletters of reference refer to like parts, and in which the figurerepresents a perspective view of the machine.

This invention is in that line of cultivators in which the driver isenabled to ride thereon, and, by means of various mechanisms, controlthe paths of the cultivator-blades.

Our invention consists, essentially, of a frame pivoted near its centerto the axle-tree of the cultivator, a seat fixed upon the rear end ofsaid frame, and connections joining the opposite end of said frame tothe plow-blade frames pivoted as in other machinesof the class.

In the drawing, A is the frame, pivoted at B to the axle-tree C, andhaving at its rear end the drivers' seat D. The beams E, to which aresecured the plows F, are pivoted at E to the swivels G, depending fromthe framework H, by means of the studs G, as in other cultivators of thekind. The forward end of the frame A is connected by chains'or othercouplings to the beams E at S, so that a downward movement of the seat Draises the plows F. The driver, sitting in the seat D, rests his feetupon the beams E, they being retained in place thereon by means ofstirrups V. The leverage of the frame A is so altered by shift ing thefulcrum-bolt B that the weight of the driver upon the seat D shall alittle more than counterbalance the beams E and their attached plows F.Therefore, by resting. more or less of his weight upon both or either ofthe beams E their vertical positions are changed to suit theinequalities of the ground.

As shown in the drawing, the bearings B have several bolt-holes throughthem, and in the side beams of the frame Aare similar holes in linetherewith. By shifting the bolts B from one to the other of thebolt-holes, the leverage of the said frame is, without changing itsposition, increased or diminished, as desired. This adjustment isnecessitated by the variations in the weights of the drivers.

;In case a boy is running this cultivator, the weight of the beams E andattached blades might overbalance him and tend to throw him up out ofreach of the said beams E. To prevent such upward movement, we providethe lever L, whose lower end projects beneath the cross-bar N. By meansof the toothed disk M, to which said lever is pivoted, and suitablecatch to engage therewith, thesaid lever L is locked at any desiredangle and the frame A held thereby.

To permit one beam E to rise as the other one is lowered, or evenretained at thesame level, or the said beams to be swung from side toside, we suspend said beams E from the opposite ends of a single chain,which'passes over apulley secured to the front end of the pivoted frameA. I By this construction the chain S can give way to either one beam orthe other,

heights.

To adapt this cultivator to drivers of different stature the chain S canbe lengthened or shortened by hooking different ones of the linkscomposing it to the hooks S, by which it is held to the beams E.

Although we have shown in thedrawing and described a chain, S, toconnect the frame A to the beams E, we do not restrict ourselves to thesame. A wire rope, strap, or other flexible bond can of course besubstituted for the chain shown. I

To permit the variable vertical and horizon-' tal movements of the twobeams E relatively to each other, there may be several modifications ofthe device which we have shown. In place of the pulley P and singlechain S, a short bar may be pivoted at its center to the front end ofthe frame A, and rods, chains, or cords extend from the ends of said barto the beamsE. The former device we deem, however, the more preferable.

By means of the yoke B, secured at its ends to the beams E, these latterare retained at the same distance apart. The stirrups B have two or morebolt-holes, to enable the beams E to be adjusted to suit any width ofrow in and so permit the desired variation in theirwhich the corn may beplanted. These stirrups B being held to the beams E by a verti cal bolt,and the yoke B being pivoted by a horizontal pin or bolt to saidstirrups, said yoke is held to said beams by a. form of universal joint, which permits the required swinging of said beams.

\Vhat we claim as our invention is 1. I11 a cultivator, aframe centrallypivoted to the axle or frame of the cultivator, and having a seat uponits rear end, in combination with a pulley secured to the forward end ofsaid pivoted frame, and a chain or other flexible bond passing over saidpulley and fastened at its ends to the plow-beams of the cultivator,whereby the weight of the driver in said seat shall support saidplow-beams and permit them unequal and opposite vertical motion, as setforth.

2. The frame A, seat D, and bearings B, in combination with the pulley1, chain S, and the beams E of a cultivator, for the purpose described.

3. The frame A, seat D, bearings B, and pulley I, in combination withthe chain S, hooks S, beams E of a cultivator, the yoke R, and stirrupsR, substantially as specified.

4. In a cultivator, the frame A, having several bolt-holes therethrough,in combination with the bearings B, having corresponding bolt-holes, andpivoted to the axle or frame of a cultivator, and the bolts or pins B,whereby the leverage of said frame A may be changed without altering thelongitudinal position of the same.

5. The combination, in a cultivator, of a frame centrally pivoted to theaxle or frame thereof, and having a seat upon its rear end, and meanswhereby the plow-beams are suspended from the front end of the saidpivoted frame, so that these plow-beams shall counterpoise each otherand enable the elevation and depression of one to oppositely affect theother, for the purpose set forth.

In testimony that we claim the foregoinginvention we have hereunto setour hands this 27th day of December, A. D. 1883.
